Stop flicking IsAttachment false and then true in AttachmentsModule.UpdateAttachmentPosition() in order to avoid a hud update race condition.

Browse Source 
Previously, setting IsAttachment to false then true was necessary to serialize the updated attachment object information.
However, UpdateAttachmentPosition no longer does this update.
Whilst IsAttachment is set to false there is a race condition where the update thread can wrongly send hud object updates to clients that do not own the hud, resulting in screen artifacts.
